travian for sure. Cheating was so rampant in travian that i quit the game out of sheer frustration because the mods wouldn't do anything about it. Aside from that the game was incredibly unbalanced.

Miniconomy was very boring, there were so few people there that the ingame economy couldn't be supported and if you did bother to buy credits for the game you'd be 100% sure of victory, because noone else would.

I've tried a few more games that I found tedious or boring or simply not to my liking, but I can't say those were the worst games I've ever played.

Club Penguin (lolol) and all of those AdventureQuest/DragonFable games. I can't believe people actually PAY for those games. o__o; Not a big fan of games like Travian and Ikariam either, though Ikariam is kinda better. ish. >>
